@TP-Link_Deco Already tried that, as I mentioned i another post, but it refuses to update. It "uploads" the BIN file, but then it doesn't update at all.

@TP-Link_Deco Just checked, the app says "Your system is updated", but it's still on 1.4.2. The same thing shows up on the Web UI. So, I guess it's not really updated yet, or the update is buggy.

@TP-Link_Deco The update is not showing up on the App (iOS), and even after downloading the firmware manually (from here), the web interface doesn't even start the upgrade. Is it busted or something?...

Looks like the same problem affecting the M5 is causing issues with the M4. It connects via WPA2-TKIP, without having an option to set it up as AES, and shows a huge alert on iOS 14. Any news of when...
